Kinda surprising that the joint statement about the MtGox insolvency statement came out before the MtGox insolvency statement. I have no reason to doubt it, just point how MtGox even screwed up a press release.
Failing to announce their insolvency to the world themselves was probably the last straw of their incommensurable incompetence.
If they really are insolvent...then they probably don't have the funds to do a PR, or should legally allocate those funds for distribution among their creditors. I'd guess their CEO or lawyer would just make a statement to the press.
